Door alignment mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerator doors often lack visually appealing alignment, with inconsistent longitudinal and lateral gaps due to manufacturing tolerances, leading to a desire for adjustable door positioning mechanisms to ensure even spacing and aesthetic appeal.
Innovation Solution
A door alignment mechanism comprising a plate fixedly attached to the door hinge, with a translational coupling mechanism allowing the refrigerator door to move between multiple positions relative to the plate, utilizing a track and movement elements like worm gears and rack gears to adjust the door's location, enabling precise adjustment of longitudinal and lateral gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional fixed door installation is used, then manufacturing simplicity is maintained, but door alignment precision deteriorates due to manufacturing tolerances
Solution Approach 1:
The patent implements a dynamic adjustment mechanism where the door can be repositioned along the hinge assembly between multiple predetermined positions. The hinge assembly includes a hinge body with an elongated slot and a hinge arm with a movable element that engages with the slot, allowing the door to transition between fixed alignment positions while maintaining structural stability when positioned.
Solution Approach 2:
The hinge assembly is segmented into distinct components: a hinge body with an elongated slot, a hinge arm with a movable element, and a door assembly. This segmentation allows independent adjustment of each component to achieve precise door alignment while maintaining manufacturing simplicity for each individual part.
2Manufacturing precision
If adjustable door positioning mechanism is implemented, then door alignment precision is improved, but device complexity increases due to additional components
Solution Approach 1:
The adjustment mechanism is designed to be self-contained within the hinge assembly, allowing the door to be repositioned by simply moving the door assembly along the predetermined path defined by the elongated slot. The movable element automatically engages with the slot to maintain the door in the selected position without requiring additional locking mechanisms or complex adjustment procedures.
3Adaptability or versatility
If multiple predetermined positions are provided, then adaptability is improved for different alignment needs, but device complexity increases due to additional positioning mechanisms
Solution Approach 1:
The hinge assembly serves multiple functions: it acts as both the hinge mechanism for door rotation and the alignment adjustment mechanism. The elongated slot in the hinge body and the corresponding movable element work together to provide both rotational movement and positional adjustment along a predetermined path, eliminating the need for separate alignment mechanisms.

AI summary
A refrigerator door assembly includes a refrigerator door that has a recess and an alignment mechanism that includes a door hinge. A plate is fixedly attached to the door hinge and positioned at least partially within the recess of the refrigerator door. The plate includes an orienting member configured to extend along an axis of rotation of the door hinge and away from a body of the plate. The refrigerator door is movably positionable between at least a first position and a second position relative to the plate to permit adjustment of a location of the refrigerator door relative to the door hinge. The recess includes a track that slides against the plate in a linear path between the first and second positions of the refrigerator door.
